Unique micro Spider* Wafer Solenoid valve for high cycle-rate reliability
Valves available to meet many specific requirements, including low current consumption, high/low temperature operation, low leakage, media compatibility and no lubrication
In-line, sub base and manifold options
Various electrical options, including connectors, lead lengths, LEDs and surge suppression

Basic pneumatic valves for ON-OFF control, clamping, pilot signaling and logic signaling
Diaphragm poppet design requires no lubrication
Ultra low force palm button models
Flow rates from 0.2 Cv to 2.4 Cv
Available with palm actuator, foot actuator, levers, toggles, ball, plunger, roller cam and one-way roller cam operators
Valves can be mounted in-line, body mounted and most can be base or panel mounted

Unique diaphragm design requires no lubrication
Contamination tolerant for non-sticking performance
Flow rates from 0.01 Cv to 2.6 Cv
Available with manual/mechanical, piloted or solenoid actuators
Some direct acting solenoid models offer small size and low current consumption

Pneumatic actuated valves for relay and/or amplification of smaller pilot signals
Used in hazardous environments and demanding applications
Available in diaphragm poppet types, which require no lubrication, or poppet and spool types
Flow rates from 0.2 Cv to 2.4 Cv
Valve options include single air pilot, ultra low pilot/interface for weak or erratic signals, momentary air pilot providing unique control methods and double air pilot for momentary signal with maintained position
Poppet and spool valves can be mounted in-line, on a sub base, or on manifolds
Accessories include exhaust port flow controls and manifold block-off plates

Total Air Control system of miniature valves, actuators and accessories for pneumatic controls and logic systems to create time delay circuits, one-shot, reset, and ballpoint pen functions
Control options include pressure regulators, flow controls, speed controls, check valves, shuttle/quick exhaust valves
Flow rates from 0.1 Cv to 0.4 Cv
Manual/mechanical operators include ball, cam, cam with one-way actuation, fingertip, foot, knee or hand operators
Manual air valve options include pushbutton, push-pull, toggle and rocker
Air pilot operators thread onto pushbutton valves to create snap action, reset, and snap action plus reset, or simply to amplify weak pilot signals
Full range of miniature fittings and mounting brackets

Diaphragm poppet cartridge valves are designed specifically for incorporation into OEM products to become a proprietary and unrecognizable component
The basic 3-way valve can function as a 2-way, 3-way or use two for 4-way valve function
Available with manual/mechanical, piloted or solenoid actuators
